Service adaptions for mixed-criticality systems
Pengcheng Huang, Georgia Giannopoulou, Nikolay Stoimenov, Lothar Thiele · 2014
Complex embedded systems are typically mixed-critical, where heterogeneous guarantees must be provided for functionalities of different criticalities. We study in this paper the reconfiguration of services provided to low criticality tasks in reaction to the overruns of high criticality tasks. We further investigate the quantification of the resetting time of the system services. For both service reconfiguration and resetting, we derive tight analysis results under Earliest Deadline First (EDF) scheduling.
